Implementing an integrated diabetic foot care programme in Ireland: podiatrists' experience.

BACKGROUND: International evidence suggests that an integrated multidisciplinary approach to diabetic foot management is necessary to prevent ulceration and progression to amputation. Many health systems have introduced policies or models of care supporting the introduction of this evidence into practice, but little is known about the experiences of those involved in implementation. This study addresses this gap by examining the experiences of podiatrists providing integrated diabetic foot care. METHODS: Between October 2017 and April 2018, an online survey comprising closed and open-ended questions on podiatrists' demographics, clinical activity, links with other services, continuous professional development activities and experiences of implementing the Model of Care was administered to podiatrists (n = 73) working for Ireland's Health Service Executive in the community and hospital setting. Data were analysed using descriptive statistics and qualitative content analysis. RESULTS: The response rate was 68% (n = 50), with 46% (n = 23), 38% (n = 19) and 16% (n = 8) working across hospital, community and both settings, respectively. Most reported treating high-risk patients (66%), those with active foot disease (61%) and educating people about the risk of diabetes to the lower limb (80%). Reported challenges towards integrated diabetic foot care include a perceived lack of awareness of the role of podiatry amongst other healthcare professionals, poor integration between hospital and community podiatry services, especially where new services had been developed, and insufficient number of podiatrists to meet service demands. CONCLUSION: Previous evidence has shown that there is often a gap between what is set out by a policy and what it looks like when delivered to service users. Results from the current study support this, highlighting that while most podiatrists work in line with national recommendations, there are specific gaps and challenges that need to be addressed to ensure successful policy implementation.

The characteristics and effectiveness of pregnancy yoga interventions: a systematic review and meta-analysis.

BACKGROUND: Yoga is a popular mind-body medicine frequently recommended to pregnant women. Gaps remain in our understanding of the core components of effective pregnancy yoga programmes. This systematic review and meta-analysis examined the characteristics and effectiveness of pregnancy yoga interventions, incorporating the FITT (frequency, intensity, time/duration and type) principle of exercise prescription. METHODS: Nine electronic databases were searched: MEDLINE, PsycINFO, EMBASE, CINAHL, WHOLiS, AMED, ScieLo, ASSIA and Web of Science. Randomised control trials and quasi-experimental studies examining pregnancy yoga interventions were eligible. Covidence was used to screen titles, abstracts, and full-text articles. Outcomes of interest were stress, anxiety, depression, quality of life, labour duration, pain management in labour and mode of birth. The Cochrane Collaboration's Risk of Bias Assessment tool was used to assess methodological quality of studies and GRADE criteria (GRADEpro) evaluated quality of the evidence. Meta-analysis was performed using RevMan 5.3. RESULTS: Of 862 citations retrieved, 31 studies met inclusion criteria. Twenty-nine studies with 2217 pregnant women were included for meta-analysis. Pregnancy yoga interventions reduced anxiety (SMD: -0.91; 95% CI: - 1.49 to - 0.33; p = 0.002), depression (SMD: -0.47; 95% CI: - 0.9 to - 0.04, P = 0.03) and perceived stress (SMD: -1.03; 95% CI: - 1.55 to - 0.52; p < 0.001). Yoga interventions also reduced duration of labour (MD = - 117.75; 95% CI - 153.80 to - 81.71, p < 0.001) and, increased odds of normal vaginal birth (OR 2.58; 95% CI 1.46-4.56, p < 0.001) and tolerance for pain. The quality of evidence (GRADE criteria) was low to very low for all outcomes. Twelve or more yoga sessions delivered weekly/bi-weekly had a statistically significant impact on mode of birth, while 12 or more yoga sessions of long duration (> 60 min) had a statistically significant impact on perceived stress. CONCLUSION: The evidence highlights positive effects of pregnancy yoga on anxiety, depression, perceived stress, mode of birth and duration of labour.

A multi-method quality improvement approach to systematically improve and promote the quality of national health and social care information.

Safe and reliable healthcare depends on access to health information that is accurate, valid, reliable, timely, relevant, legible and complete. National data collections are repositories of health and social care data and play a crucial role in healthcare planning and clinical decision-making. We describe the development of an evidence-informed multi-method quality improvement program aimed to improve the quality of health and social care data in Ireland. Specific components involved: development of guidance to support implementation of health information standards; review program to assess compliance with standards; and educating health information stakeholders about health data and information quality. Observations from implementation of the program indicate enhanced health information stakeholder awareness of, and increased adoption of information management standards. The methodology used in the review program has proved to be a robust approach to identify areas of good practice and opportunities for improvement in information management practices. There has been positive adoption of the program among organisations reviewed and acceptance of the proposed recommendations. Early indications are that this multi-method approach will drive improvements in information management practices, leading to an improvement in health and social care data quality in Ireland. Aspects of this approach may be adapted to meet the needs of other countries.

Epidemiology of undiagnosed depression in people with diabetes mellitus: a comparative analysis of Ireland, England and the USA.

OBJECTIVES: Improving detection of depression in people with diabetes is recommended. However, little is known about how different health systems compare in depression detection. We estimated and compared the (1) prevalence of depression detection in people with and without diabetes, and (2) association between diabetes and undiagnosed depression across three health systems. DESIGN: Cross-sectional analysis of three nationally representative studies: The Irish Longitudinal Study on Ageing, the English Longitudinal Study on Ageing and the Health and Retirement Study. SETTING: Community-dwelling adults in Ireland, England and the USA. PARTICIPANTS: Adults aged ≥50 years. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was depression diagnosis. The secondary outcome was any depression. Any depression was defined by the presence of self-reported doctor-diagnosed depression or current depression symptoms on the Centre for Epidemiological Studies-Depression scale. Depression diagnosis was categorised as: undiagnosed, symptomatic and diagnosed, and asymptomatic and diagnosed. We estimated age-standardised prevalence of depression diagnosis by country and diabetes status. Anyone who self-reported having ever received a doctor diagnosis of diabetes was classified as having diabetes. Among respondents with depression, we estimated the association between diabetes and undiagnosed depression by country using multivariable logistic regression. RESULTS: The prevalence of depression (diagnosed and undiagnosed) was higher in people with diabetes in each country with absolute rates varying by country; undiagnosed prevalence (Ireland: diabetes 10.1% (95% CI 7.5% to 12.8%) vs no diabetes 7.5% (95% CI 6.8% to 8.2%), England: diabetes 19.3% (95% CI 16.5% to 22.2%) vs no diabetes 11.8% (95% CI 11.0% to 12.6%), USA: diabetes 7.4% (95% CI 6.4% to 8.4%) vs no diabetes 6.1% (95% CI 5.7% to 6.6%)). In the fully adjusted model, there was no clear pattern of association between diabetes status and undiagnosed depression; Ireland: OR=0.82 (95% CI 0.5 to 1.3), England: OR=1.47 (95% CI 1.0 to 2.1), USA: OR=0.80 (95% CI 0.7 to 1.0). CONCLUSIONS: Although undiagnosed depression was more prevalent among people with diabetes, the relationship between diabetes and undiagnosed depression differed by country. Targeted efforts are needed to improve depression detection among community-dwelling older adults, particularly those with diabetes.

Barriers and enablers to screening and diagnosing diabetes distress and depression in people with type 2 diabetes mellitus: A qualitative evidence synthesis.

AIM: Synthesise qualitative evidence of healthcare professionals' (HCP) experiences of diabetes distress and depression screening in people with type 2 diabetes (T2DM) in primary care to identify HCP barriers and enablers to screening implementation. METHODS: Searched six electronic databases in October 2020 for qualitative studies exploring HCPs' experiences of diabetes distress and depression screening in T2DM populations. Applying a best-fit framework synthesis, data were coded to the theoretical domains framework (TDF), followed by thematic analysis of data that did not fit the TDF. Study quality and confidence in findings were assessed using CASP and GRADE-CERQual respectively. FINDINGS: Of 4942 unique records identified, 10 articles were included. We identified fifteen barriers and enablers in 8 TDF domains and 1 new domain; people with T2DM factors. One barrier (poor awareness about the rationale for screening) and 2 enablers (perceived impacts on T2DM care, receiving financial reimbursement) were assessed as findings of high confidence. CONCLUSION: HCPs experience many barriers and enablers to diabetes distress and depression screening among people with T2DM in primary care. Future interventions and policies should ensure HCPs understand the rationale for screening, highlight the benefits of screening, resource screening appropriately and address HCP group specific barriers.

Infants Diagnosed with Athyreosis on Scintigraphy May Have a Gland Present on Ultrasound and Have Transient Congenital Hypothyroidism.

Scintigraphy using technetium-99m (99mTc) is the gold standard for imaging the thyroid gland in infants with congenital hypothyroidism (CHT) and is the most reliable method of diagnosing an ectopic thyroid gland. One of the limitations of scintigraphy is the possibility that no uptake is detected despite the presence of thyroid tissue, leading to the spurious diagnosis of athyreosis. Thyroid ultrasound is a useful adjunct to detect thyroid tissue in the absence of 99mTc uptake. AIMS: We aimed to describe the incidence of sonographically detectable in situ thyroid glands in infants scintigraphically diagnosed with athyreosis using 99mTc and to describe the clinical characteristics and natural history in these infants. METHODS: The newborn screening records of all infants diagnosed with CHT between 2007 and 2016 were reviewed. Those diagnosed with CHT and athyreosis confirmed on scintigraphy were invited to attend a thyroid ultrasound. RESULTS: Of the 488 infants diagnosed with CHT during the study period, 18/73 (24.6%) infants with absent uptake on scintigraphy had thyroid tissue visualised on ultrasound (3 hypoplastic thyroid glands and 15 eutopic glands). The median serum thyroid-stimulating hormone (TSH) concentration at diagnosis was significantly lower than that in infants with confirmed athyreosis (no gland on ultrasound and no uptake on scintigraphy) (74 vs. 270 mU/L), and median free T4 concentration at diagnosis was higher (11.9 vs. 3.9 pmol/L). Six of 10 (60%) infants with no uptake on scintigraphy but a eutopic gland on ultrasound had transient CHT. CONCLUSION: Absent uptake on scintigraphy in infants with CHT does not rule out a eutopic gland, especially in infants with less elevated TSH concentrations. Clinically, adding thyroid ultrasound to the diagnostic evaluation of infants who have athyreosis on scintigraphy may avoid committing some infants with presumed athyreosis to lifelong levothyroxine treatment.

A core outcome set for trials of infant-feeding interventions to prevent childhood obesity.

BACKGROUND: Standardisation of outcomes measured and reported in trials of infant-feeding interventions to prevent childhood obesity is essential to evaluate and synthesise intervention effects. The aim of this study is to develop an infant-feeding core outcome set for use in randomised trials of infant-feeding interventions, with children ≤1 year old, to prevent childhood obesity. METHODS: Core outcome set development followed four stages: (1) systematic review of outcomes reported in the extant literature; (2) meeting with national and international stakeholders to discuss and clarify identified outcomes; (3) e-Delphi study with national and international stakeholders to prioritise outcomes; (4) meeting with national and international stakeholders to reach consensus on outcomes. Stakeholders in stages 2-4 were paediatricians, general practitioners, nurses, midwives, non-clinician researchers, parents, dieticians, nutritionists, and childcare providers. RESULTS: Twenty-six outcomes were identified for inclusion in the core outcome set. These were grouped in nine outcome domains: 'breastfeeding and formula feeding', 'introduction of solids', 'parent feeding practices and styles', 'parent knowledge and beliefs', 'practical feeding', 'food environment', 'dietary intake', 'perceptions of infant behaviour and preferences', and 'child weight'. CONCLUSIONS: The core outcome set identified in this study is the minimum that should be measured and reported in trials of infant-feeding interventions to prevent childhood obesity. This standardisation of outcomes will enable more comprehensive examination and synthesis of the effects of infant-feeding interventions to prevent childhood obesity.

'Sink or Swim': A Qualitative Study to Understand How and Why Nurses Adapt to Support the Implementation of Integrated Diabetes Care.

BACKGROUND: Integrated care, organising care delivery within and between services, is an approach to improve the quality of care. Existing specialist roles have evolved to work across settings and services to integrate care. However, there is limited insight into how these expanded roles are implemented, including how they may be shaped by context. This paper examines how new diabetes nurse specialists working across care boundaries, together with hospital-based diabetes nurse specialists, adapt to support the implementation of integrated care. METHODS: We conducted semi-structured focus groups and interviews with diabetes nurse specialists purposively sampled by work setting and health service region (n = 30). Analysis was data-driven, coding actions or processes to stay closer to the data and using In Vivo codes to preserve meaning. FINDINGS: Community nurse specialists described facing a choice of "sink or swim" when appointed with limited guidance on their role. To 'swim' and implement their role, required them to use their initiative and adapt to the local context. When first appointed, both community and hospital nurse specialists actively managed misconceptions of their role by other staff. To establish clinics in general practices, community nurse specialists capitalised on professional contacts to access GPs who might utilise their role. They built GP trust by adopting practice norms and responding to individual needs. They adapted to the lack of a multidisciplinary team "safety net" in the community, by "practicing at a higher level", working more autonomously. Developing professional links and pursuing on-going education was a way to create an alternative 'safety net' so as to feel confident in their clinical decision-making when working in the community. Workarounds facilitated information flow (i.e. patient blood results, treatment, and appointments) between settings in the absence of an electronic record shared between general practices and hospital settings. CONCLUSIONS: Flexibility and innovation facilitates a new way of working across boundaries. Successful implementation of nurse specialist-led integrated care requires strategies to address elements in the inner (differences in practice organisation, role acceptance) and outer (information systems) context.

Coeliac screening in a high-risk population: paediatric type 1 diabetes-a review of current guidelines and practice.

BACKGROUND AND AIMS: Coeliac disease (CD) is more common in those with type 1 diabetes mellitus (T1DM) and may be asymptomatic despite the presence of intestinal histological changes. Optimal screening practice guidelines differ internationally. We undertook a retrospective audit to determine the efficacy of current screening practice for CD in T1DM in our centre. METHODS: All children and adolescents < 16 years, diagnosed with T1DM in our service and continuing to attend the service in January 2017 were included. Data on CD screening was collected and compared to current NICE, NASPGHAN and ESPGHAN guidelines. RESULTS: Of the 355 patients attending our service, 253 attended from T1DM diagnosis and all had CD screening performed in our centre. In 37 of 253 patients, IgA-TTG was positive, providing a cumulative prevalence of 14.6%. Of these, 31(83.78%) with an elevated TTG on screening had no recorded gastrointestinal symptoms or CD-related clinical signs. Of the 35 TTG plus EMA-positive patients, 22/35 (59.46%) had diagnostic endoscopic biopsy. Nineteen (83.4%) had CD confirmed, 1 (4.54%) had negative biopsy and 2 (9%) had equivocal, non-diagnostic changes. CONCLUSIONS: Timely diagnosis of CD can prevent chronic ill health in affected individuals, and in patients with T1DM, CD is an independent risk factor for increased morbidity and mortality. Given the high prevalence of atypical symptoms and silent CD in those with T1DM, in this and other studies, and the benefits of detection and treatment of CD, screening is essential. Large-scale data collection allowing for the development of evidence-based guidelines is required.

Developing a core outcome set for childhood obesity prevention: A systematic review.

Synthesis of effects of infant feeding interventions to prevent childhood obesity is limited by outcome measurement and reporting heterogeneity. Core outcome sets (COSs) represent standardised approaches to outcome selection and reporting. The aim of this review is to identify feeding outcomes used in infant feeding studies to inform an infant feeding COS for obesity prevention interventions. The databases EMBASE, Medline, CINAHL, CENTRAL, and PsycINFO searched from inception to February 2017. Studies eligible for inclusion must examine any infant feeding outcome in children ≤1 year. Feeding outcomes include those measured using self-report and/or observational methods and include dietary intake, parent-child interaction, and parental beliefs, among others. Data were extracted using a standardised data extraction form. Outcomes were assigned to outcome domains using an inductive, iterative process with a multidisciplinary team. We identified 82 unique outcomes, representing nine outcome domains. Outcome domains were "breast and formula feeding," "introduction of solids," "parent feeding practices and styles," "parent knowledge and beliefs," "practical feeding," "food environment," "dietary intake," "perceptions of infant behaviour and preferences," and "child weight outcomes." Heterogeneity in definition and frequency of outcomes was noted in reviewed studies. "Introduction of solids" (59.5%) and "breastfeeding duration" (55.5%) were the most frequently reported outcomes. Infant feeding studies focus predominantly on consumption of milks and solids and infant weight. Less focus is given to modifiable parental and environmental factors. An infant feeding COS can minimise heterogeneity in selection and reporting of infant feeding outcomes for childhood obesity prevention interventions.

Optimal Timing of Repeat Newborn Screening for Congenital Hypothyroidism in Preterm Infants to Detect Delayed Thyroid-Stimulating Hormone Elevation.

OBJECTIVES: To evaluate the timing of a delayed rise in thyroid-stimulating hormone (TSH) levels in preterm infants with congenital hypothyroidism, and to determine whether cases of congenital hypothyroidism would be missed by using current consensus guidelines of repeat screening at approximately 2 weeks of age or 2 weeks after the first screening. STUDY DESIGN: The study was performed over a 13-year period (January 2004-December 2016). Whole-blood TSH samples were collected between 72 and 120 hours after birth. Repeat samples were collected weekly in preterm infants until the infant was term-corrected (37 weeks' gestation). Patients were followed up to determine whether congenital hypothyroidism was permanent or transient. RESULTS: Twenty-seven (50.9%) preterm infants born at <33 weeks of gestation who were diagnosed with congenital hypothyroidism had delayed TSH elevation and would not have been detected on first newborn screen. Twelve of these infants (40.7%) with delayed TSH elevation had decompensated hypothyroidism at diagnosis (free thyroxine [FT4] <10 pmol/L), and 4 had severe congenital hypothyroidism (FT4 <5.5 pmol/L) at diagnosis. If screening had been repeated only at 2 weeks of life, 13 infants (48%) with delayed TSH elevation would not have been identified. Of the 27 infants with delayed TSH elevation, 6 (22%) have permanent congenital hypothyroidism, and another 12 will be reevaluated at age 3 years. CONCLUSION: Repeat screening for congenital hypothyroidism in preterm infants is necessary to avoid missing cases of congenital hypothyroidism with delayed TSH elevation. Repeat screening once at 2 weeks of life will miss infants with delayed TSH elevation and decompensated permanent congenital hypothyroidism.

Barriers and enablers to screening and diagnosing depression and diabetes distress in people with type 2 diabetes mellitus; protocol of a qualitative evidence synthesis.

Background: Depression and diabetes distress are common in people with type 2 diabetes (T2DM). These conditions are independently associated with poorer T2DM outcomes and increased healthcare utilisation and costs. Questions remain regarding the most appropriate ways of initially detecting depression and diabetes distress in this group. Diabetes guidelines recommend depression screening in primary care for people with T2DM but their implementation in practice is suboptimal. As health care professionals influence detection practices, their perceptions and experiences of these guidelines can improve understanding of aspects of the guidelines that work, and those which are more difficult to implement in practice. This study describes the protocol for a qualitative evidence synthesis of primary care health professionals' perceived barriers and enablers to screen for and diagnose depression and diabetes distress in people with T2DM. Methods and analysis: Primary qualitative and mixed method studies will be identified using a systematic search of electronic databases and the CLUSTER (Citations, Lead authors, Unpublished materials, Scholar searches, Theories, Early examples, Related projects) approach. We selected 'best-fit framework synthesis' as the approach to synthesise primary data using the RETREAT (Review question-Epistemology-Time/Timescale-Resources-Expertise-Audience and purpose-Type of Data) framework. Quality appraisal of primary studies and confidence in the overall review findings will be determined using the CASP (Critical Appraisal Skills Programme) and the GRADE-CERQual (Grading of Recommendations Assessment, Development, and Evaluation Confidence in the Evidence from Reviews of Qualitative research), respectively. Discussion: The planned review will provide the first, single point of reference of the available synthesised qualitative evidence on this topic. It will apply recommended approaches to ensure rigor and robustness of study and contribute meaningfully to understanding of how depression and diabetes distress can be initially detected in people with T2DM. This protocol is awaiting processing by the International Prospective Register of Systematic Reviews (PROSPERO) [ID number 145483].

Incidence of Congenital Hypothyroidism Over 37 Years in Ireland.

BACKGROUND AND OBJECTIVES: Congenital hypothyroidism (CHT) is one of the most common preventable causes of learning disability. Newborn screening with whole-blood thyroid-stimulating hormone measurements was introduced in the Republic of Ireland in 1979 and is coordinated from a single center with an unchanged protocol since its inception. Our objective in this study was to describe the incidence of CHT in the Republic of Ireland over the past 37 years in the context of a complete national population and an unchanged screening protocol. METHODS: The newborn screening records of all individuals who were diagnosed with CHT between 1979 and 2016 were reviewed. Infants with positive screening results had a whole-blood thyroid-stimulating hormone value of ≥15 mU/L at 72 to 120 hours of life; values of 8 to 15 mU/L required a repeat whole-blood screening test. RESULTS: Of 2 361 174 infants who were screened between July 1979 and December 2016, 1063 (662 girls) were diagnosed with CHT (incidence: 0.45 cases per 1000 live births). The number of detected cases increased from 0.27 cases per 1000 live births treated between 1979 and 1991 to 0.41 cases per 1000 live births treated between 1992 and 2004 to 0.65 cases per 1000 live births treated between 2005 and 2016. The increase in detected cases of CHT was predominantly in the normal or hyperplastic gland category. CONCLUSIONS: The incidence of CHT has increased significantly in the Republic of Ireland over the past 37 years despite a consistent screening cutoff. The increased rate was not explained by an increased survival rate of preterm infants or a changing population heterogeneity.

Permanent Decompensated Congenital Hypothyroidism in Newborns with Whole-Blood Thyroid-Stimulating Hormone Concentrations between 8 and 10 mU/L: The Case for Lowering the Threshold.

BACKGROUND: Congenital hypothyroidism (CHT) has a reported incidence of approximately 1 in 2,000-4,000 births. There is no consensus on the optimal cut-off whole-blood thyroid-stimulating hormone (TSH) concentration that should be used for newborn screening (NBS). The NBS programme in the Republic of Ireland has used a cut-off of 8 mU/L since 1979. The aim of this study was to determine if raising the cut-off to 10 mU/L would have resulted in undetected cases of permanent or decompensated CHT. METHODS: All cases of CHT with a screening whole-blood TSH concentration between 8.0 and 9.9 mU/L were identified from the Republic of Ireland's NBS programme. Baseline demographics and imaging results were recorded. All cases over 3 years of age were evaluated to determine if CHT was permanent or transient. RESULTS: Of 2,361,174 infants screened in the Republic of Ireland between July 1979 and December 2016, a total of 1,063 babies were diagnosed with CHT and treated with levothyroxine. This included 33 (3.5%) infants with a whole-blood TSH concentration between 8 and 9.9 mU/L. Thirteen of these 33 infants had decompensated hypothyroidism with low plasma free thyroxine level at diagnosis and 9 (41%) of the 21 evaluable cases have confirmed permanent CHT. CONCLUSION: Although lowering screening TSH cut-offs can increase the cost of NBS, as well as anxiety for families, many infants with borderline increases in whole-blood TSH concentrations on NBS have persistent CHT and low thyroxine concentrations in infancy. We recommend that this is considered when developing and reviewing NBS protocols for identifying infants with CHT.

Development of an infant feeding core outcome set for childhood obesity interventions: study protocol.

BACKGROUND: Childhood obesity is a significant public health challenge that affects approximately one in five children worldwide. Infant feeding practices are implicated in the aetiology of childhood obesity. Infant feeding interventions for childhood obesity are increasingly popular but outcome reporting is inconsistent across trials. Lack of standardisation limits examination of intervention effects and mechanisms of change. The aim of the current project is to develop a core set of infant feeding outcomes for children ≤ 1 year old, to be evaluated in childhood obesity intervention trials. METHODS: This project will use similar methodology to previous core outcome development research. An infant feeding core outcome set (COS) will be developed in four stages: (1) a systematic review of the literature, (2) discussion and clarification of outcomes in a meeting involving multiple stakeholder perspectives, (3) prioritisation of outcomes using the Delphi technique with an expert panel of stakeholders, and (4) achieving consensus on the COS using the nominal group technique (NGT) consensus meeting. An online Delphi survey will be conducted following the NGT meeting to prioritise outcomes identified in the systematic review. An NGT meeting will be conducted with groups of health professionals, non-clinician researchers, and parents of infants ≤ 1 year old, to achieve final consensus on the infant feeding COS. DISCUSSION: This study aims to develop a core outcome set of infant feeding outcomes for randomised infant feeding studies to prevent childhood obesity. This research will improve examination and syntheses of the outcomes of such studies to prevent and reduce childhood obesity.

Oral administration of diluted nasal desmopressin in managing neonatal central diabetes insipidus.

BACKGROUND: Neonatal central diabetes insipidus (NCDI) remains a therapeutic challenge, as extremely low doses of enteral desmopressin cannot be titrated with current preparations. The aim of this study was to describe the use of orally administered dilute desmopressin in NCDI. METHODS: Nasal desmopressin (100 µg/mL) was diluted in 0.9% saline to 10 µg/mL. Infants were treated with 1-5 µg and doses were titrated to a twice-daily regimen. The feed volume was 150 mL/kg/day and titrated according to weight gain. RESULTS: Five infants aged 6-105 days were included. Stabilizing treatment doses ranged from 2 to 5 µg twice daily in neonates, and 12 µg twice daily in the older infant who was diagnosed at 105 days. CONCLUSIONS: Dilution of nasal desmopressin with saline facilitates safe administration and dose titration in NCDI. We recommend considering this therapeutic approach to NCDI, particularly in small infants or where alternative treatment regimens have been unsuccessful.

Expanding the clinical spectrum of chromosome 15q26 terminal deletions associated with IGF-1 resistance.

Haploinsufficiency of the insulin-like growth factor-1 receptor (IGF1R) gene on chromosome 15q26.3 is associated with impaired prenatal and postnatal growth, developmental delay, dysmorphic features and skeletal abnormalities. Terminal deletions of chromosome 15q26 arising more proximally may also be associated with congenital heart disease, epilepsy, diaphragmatic hernia and renal anomalies. We report three additional cases of 15q26 terminal deletions with novel features which may further expand the spectrum of this rarely reported contiguous gene syndrome. Phenotypic features including neonatal lymphedema, aplasia cutis congenita and aortic root dilatation have not been reported previously. Similarly, laboratory features of insulin-like growth factor 1 (IGF-1) resistance are described, including markedly elevated IGF-1 of up to +4.7 SDS. In one patient, the elevated IGF-1 declined over time and this coincided with a period of spontaneous growth acceleration. CONCLUSION: Deletions of 15q26 are a potential risk factor for aortic root dilatation, neonatal lymphedema and aplasia cutis in addition to causing growth restriction. What is Known: • Terminal deletions of chromosome 15q26 are associated with impaired prenatal and postnatal growth, developmental delay, dysmorphic features and skeletal abnormalities. What is New: • Neonatal lymphedema, aplasia cutis congenita and aortic root dilatation have not been previously described in 15q26 terminal deletions and may represent novel features. • IGF-1 levels may be increased up to 4.7 SDS.

Aromatase inhibitors for short stature in male children and adolescents.

BACKGROUND: As a result of the essential role of oestrogens in epiphyseal closure, aromatase inhibitors have been trialled as an intervention to improve height outcomes in male children and adolescents by inhibiting the conversion of testosterone to oestradiol. OBJECTIVES: To assess the effects of aromatase inhibitors in male children and adolescents with short stature. SEARCH METHODS: To identify relevant trials, we searched the Cochrane Library (2014, Issue 7), MEDLINE, EMBASE, and the World Health Organization (WHO) ICTRP trial register from their inception until August 2014. In addition, we conducted citation searches and screened reference lists of included trials. SELECTION CRITERIA: We included randomised controlled trials (RCTs) if they compared use of an aromatase inhibitor with placebo in male children and adolescents with short stature. DATA COLLECTION AND ANALYSIS: Two authors independently screened titles and abstracts for relevance. Both authors carried out screening for inclusion, data extraction, and risk of bias assessment, with any disagreements resolved following discussion. We assessed trials for quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) instrument. We contacted study authors regarding missing information. Primary outcomes were final or near-final height, adverse events, and health-related quality of life. Secondary outcomes included all-cause mortality, cognitive outcomes, socioeconomic effects, laboratory measures, short-term growth parameters, and assessment of effects on bone health. Meta-analysis was not appropriate due to the substantial clinical heterogeneity between trials; we presented the findings of the review in narrative format. MAIN RESULTS: We included four RCTs involving 207 participants (84 on interventions) in the review. Trials included males with constitutional delay of growth and puberty (CDGP), idiopathic short stature (ISS), and growth hormone (GH) deficiency. Three of the trials had an overall low or unclear risk of bias for primary outcomes. Short-term growth outcomes, such as predicted adult height, improved in all trials. Just one trial reported the primary outcome of final and near-final height as an extension under non-randomised conditions. None of the trials assessed health-related quality of life. One publication provided detailed information regarding the incidence of adverse events. A significant proportion (45%) of prepubertal boys with ISS treated with letrozole developed mild morphological abnormalities of their vertebrae, compared with none in the placebo group. AUTHORS' CONCLUSIONS: Available evidence suggested that aromatase inhibitors improved short-term growth outcomes. There was no evidence to support an increase in final adult height, based on limited data, with only one of four trials publishing final height data under non-randomised conditions.

An intervention study exploring the effects of providing older adult hip fracture patients with an information booklet in the early postoperative period.

AIM: To determine whether the provision of an information booklet on mobilisation improves early mobility postsurgical repair of hip fracture. BACKGROUND: Hip fracture among older people can have long-lasting consequences with the majority of patients failing to achieve their prefracture functional status. Early postoperative mobility may have a positive effect on long-term recovery. The importance of providing postoperative information on mobility has been highlighted. It is suggested that patients remain passive in their recovery when they do not understand the importance of mobilisation. DESIGN: The study used a pretest-post-test design of two treatments and a usual care control group. METHODS: Eighty-three adults postsurgical repair of hip fracture, aged 65 years and older, were recruited to the study. Participants were assigned to one of three groups, a usual care group, treatment group 1 (T(1)) usual care plus basic information booklet or treatment group 2 (T(2)) usual care plus detailed information booklet. Data collection three days postsurgery and prior to discharge included the Mini-Mental State Examination, a Demographic Questionnaire, the Elderly Mobility Scale and a Numerical Pain Scale. RESULTS: Greatest improvements in Elderly Mobility Scale scores occurred in T(1), with least changes observed in T(2). Changes did not reach significance level (p=0·105). CONCLUSION: The results of the study suggest that the provision of basic information is preferable and highlights a deficiency of education in usual care. RELEVANCE TO CLINICAL PRACTICE: Hip fracture patients should be provided with an educational booklet containing basic information on mobility to promote optimal recovery.
